product introduction:
DZH type manual biomass boiler is a vertical one barrel biomass boiler, which is a new product developed by our company in response to environmental protection policies. It uses biomass particles from harvesting wastes such as straw, sawdust and peanut shell as fuel, and the emission of flue gas is significantly reduced compared to that of coal-fired boilers, which meets national environmental protection standards. What's better is that the harvest waste can be seen everywhere, which not only turns waste into treasure, achieves energy reuse, but also has a low price, and achieves the double unit of social and economic benefits.
This boiler isa horizontal three pass fire tube boiler, using a new furnace design, the maximum measure to promote fuel combustion, so that the thermal efficiency reached 83%. Once the fuel is burned, the combustion gas enters the dust collector through the heating surface, economizer, air preheating, etc., and finally the chimney is discharged into the atmosphere, and the remaining small amount of ash falls into the slag outlet, which is used as agricultural fertilizer needed for crop growth.
Product characteristics:
1. The cylinder is composed of arch tube plate and threaded smoke pipe, so that the cylinder is changed from quasi-steel body to quasi-elastic structure, and the pulling member in the tube plate area is cancelled, and the stress is reduced. The smoke pipe in the tube plate is changed from two return trips to one return trips, which solves the problem of tube plate cracks.
2. Due to the arrangement of the rising pipe row in the lower part of the drum, the dead water area at the bottom of the drum is eliminated, so that the mud is not easy to deposit, and the high temperature area of the drum can be cooled well to prevent the bulge in the lower part of the drum.
3. High efficiency heat transfer threaded smoke pipe is used to obtain enhanced heat transfer
